The tpt wiki confirms that BREL is aluminum.

Element ideas should have creativity and actual unique useful features, not just some real world element that works exactly as it does in the real world as in the game. You think elements like EXOT, RFRG, VIBR are real elements that are just copied from google?

 I can see the logic in you're comment, but EXOT and RFRG are real; they're just not exactly like they are in tpt.  Exotic matter is substance with negative mass, which was produced in Washington State University in 2017.  Refrigerant is used in air conditioners and, of course, refrigerators.
